TRACKED TRANSMISSION SYSTEM OF HYBRID ELECTRIC VEHICLE

摘要

PURPOSE: A dynamic power transmission apparatus of a crawler hybrid electric vehicle is provided to increase whole efficiency, by performing conversion between a serial type and a parallel type freely. CONSTITUTION: An engine(10) generates driving force. A clutch(30) enables the output of the power to perform selective dynamic power transmission via a power generator(20). A propeller shaft(40) transfers the output of the engine through the clutch. A first and a second sun gear(50, 60) enable dynamic power transmission through both ends of the propeller shaft. A first and a second planetary gear unit(70, 80) receives the dynamic power from the first and the second sun gear, and then delivers the dynamic power to output shafts(51, 61). A complex planetary gear unit(90)is connected to the first and the second planetary gear unit. A first and a second traction motor(100, 110) are connected to drive the first and the second sun gear. A stirring motor(120) is connected to the first planetary gear unit and the complex planetary gear unit through a stirring shaft(121). A controller(200) controls the first and the second traction motor and the stirring motor.
